Abstract:
Pragmatic information is looked on as the next focus for natural langu age processing (NLP) research. The necessity and importance of pragmatic informa tion are analyzed firstly. It is pointed out that NLP could be charaterized as h umanity and intelligence only after pragmatic information are integrated into it . And only when syntactic, semantic and pragmatic information are all fully stud ied could computers understand the information expressed in human natural language. Thus computers could really communicate with human. Then details of pr agmatics research are introduced, including its origin, growing history and appl ications. Problems are also analyzed for its current status. As a result, pragma tic information based NLP is put forward. Then a grope research of this, i.e. th e sentence error detection and correction in the application domain of “CityGui de” Speech Recognition (SR) interface is reported. The “CityGuide” is a demo terminal for the National 863 project of “Olympics Oriented Multilingual Inform ation Service”. A method containing pragmatic information analysis is studied a nd tested using realistic corpus. Results show that the precision of Chinese SR can be improved by 29%. 
